To all whom it may concern:

Be it known that l, JOHN L. KlvLAN, a

` citizen o the United States, residin at Boston, in the` county of Suffolk and tate of: Massachusetts, have invented certain new and useful and l do hereby declare the Jfollowing to be a full, clear, and exact description ol. the invention, such as will enable others skilled in the art to which it appertains to make and use `the same.

This invention relates to jar closures and particularly to an improvement in the type of jar closure disclosed in the patent issued February 23, 1909, No. 913214.

Oneofithe, objects of the present invention is to reduce ythe number oiindividual elements going to comprise the organization an therefore to reduce the cost of assemblage oi the parts and at th'eisame time to reduce the cost of construction. Another object oi the invention is to provide parts which are readily assembled and yet which are substantial, durable, and -also accomplish the effectual 25 clamping or` a'cover on to a sealing gasket to secure the efectual closure oi: the container onwhich the cover may be arranged.

With these and other objects in view as will be rendered manifest in the following specification to those skilled in the art the inventionponsists in the construction, combination, and in details and elements of the parts as more particularly set forth in the following spec-iication with relation to the embodiments of the invention illustrated in the accompanying drawings herein Figure 1 is a vertical, central section through the upper portion oil a fragment oi' a jar with the closure applied and clamped.

have illustrated my improved clamp as'60 applied to a convenient 'form of jar ,1,101.1 a circumferential rim or shoulder on which lis provided a gasket R to receive the flange oli the cover or top T this'latter being clearly shown in Fig. l as 'icing provided with a 65 circular groove on its top face at g for a purpose hereinafter specified. rlhe outer surface of the neck of thejar is provided with 'an annular shoulder C just below which. there is disposed a wire or ring `7 preferably of 70 such diameter as not to project above the` shoulder C. Directly and pivotally mounted on this wire ring is a toggle link or member L shown as comprising a piece of bent tin plate or suitable material of suitable width having an 0ver-turned upper ear or hub forming a hinge portion to swing on the included wire, thc hub portion k being flattened tangentially at d to abut against the adjacent surface C so that an eiiective seating or abutment between the toggle link L and the seat is secured. The lower or swinging end ofthe tog le link L is shown as rolled over to pivotal y receive the transveise bar or' a wire or other link or hoolr. member D 85 which is slightly outwardly curved when observed edgewise so as to 'freely pass over the protruding neclr portion of the bottle when the hook, of which it might be stated,'there is one on each side of the bottle, is yarranged in the clamping position Fig. l at which time the upper portion or nib d of the hook is drawn downwardly into the groove g of the cover or top T. This ldrawing down or clamping action of the hoclr or hooks D ocv curs after the cover T has been put in place, and the hook l) swung downwardly from the position shown in Fig. 2. to the position shown in Fig. 1 whereupon inasmuch' as the toggle link L swings beneath its pivot cn the ring ll] the hoolr D is placed under tension as its nib d, brin s up against the top T and its lower end, which is connected with the swinglink l1, passes toward the iai'.

As clearly shown in F ig. el. in which the hoolr is shown as swung outwardly from the surace oit the jar, the nib of the hook is formed orx a transverse bar which is curve to conform to the curvature o' thecircular groove g in the top of the jar closure so that the hook seats snugly in position against the curved surface of the groove shown in a circumferential direction and also in a vertical direction where the hook enters downwardly into the groove. By this structure the toggles are retained in an operative position irrespective of the amount of pressure which they exert. It will be further noted that the portion of the jar cover Within the circular groove g' is on a higher plane than the circumferential ridge on the outer side of the groove g. By reason of this structure, in applying the fastening members the nibs are permitted to pass over the external ridge and then engage the higher central part of the top, whereupon by pressure being applied to the members D the top can be readily centered on the jar Without being touched.

From the above it will be seen that I have provided an extremely simple means of clamping the jar closure in position and that the closure comprises a simple and inexpensive ring having pivoted at diametrically opposite points a pair of toggle links L swinging directly on the wire ring and carrying at their outer ends the wire hooks or tension members D which are designed to snugly engage the grooved portion of the cover so as to prevent accidental removal of the parts after the same have been set in clamped position and so that the hook can only be removed by first swinging -outwardly its bottom end which is connected with the toggle link L.

o prevent downward movement of the ring on which the toggle links L-L are mounted suitable means may be employed or formed upon the jar body as for instance in Fig. 3 the jar neck may he provided with acircular shoulder or projection P spaced sufficiently below the shoulder C to form a channel or groove for a reception of the wire ring W. A slightly modified form of the ring retaining device is shown in F ig. 4 in which the `support is illustrated as comprising a series of small spurs S in substitution of the bead or ring shown at P in Fig. 3.

In Figs. 6 and 7 a slightly modified form of the invention is shown and in which the hook member D is directly pivoted on the ring `W and nas its upper end bent inwardly. Pivoted in this upper end is a staple-shaped nih N the ends or' which are designed to -enter the groove in the top T. The tension of the member holds the clamp closed.

`What I desire to claim is:

1. A jar closure comprising in combination a cover having a peripheral ridge defined by an interior circular groove, and a plurality of vclamping members having downturned nibs conformed to the shape of and adapted to seat in said groove within said ridge.

2. A jar closure comprising in combination, a cover having a peripheral ridge de` fined by an interior circular groove, diametrically opposed toggle joint levers having down turned nibs on one member to engage said groove Within said ridge and an annular Wire-pivoting and frictionally securing said toggles to the neck of the jar.

. )ar closure comprising in combina-- tion a cover,l

toggles having each a locking shoulder and locking means on Vthe neck of the Jar adapted to engage said shoulders on the latter in a predeter#v the toggles to secure mined position. v y

4;. The combination of a jar having a cir! cular ridge on its neck, a cover having a peripheral ridge determinedby an interior circular groove, and toggle members adapted to engage both the ridge on the jar and that on the cover. 'i

5. i jar closure comprising; in combination, a cover having a marginalridge and a plurality of clamping members having downturned nibs adapted to seat onsaid top within said ridge.

6. As an article of manufacture. a' jar cover having on its hottorntace an annular seating surface adapted to rest on a gasket on a suitable annular seat on a jar neck, and having on its upper face a peripheral ridge determined by an interior circular groove, the bottom of said circular groove being directly over said annular scat and adapted to receive Yfastening members, whereby pressure exerted on the bottom 'of said groove will be transmitted directly to said seat.
